Physicists turn particles in chaotic orbits into liquid computers — but this fluid hardware still trails memristor rivals

Researchers in Germany built a physical reservoir computer from 400 laser-driven microscopic particles orbiting in liquid.

The system produced useful forecasting and anomaly-detection results, but its accuracy lagged far behind memristor-based hardware.

It was tunable and robust in tests, yet it depends on complex optics and does not report energy-efficiency data.

The work is an important proof of concept for liquid-based computing, but it is still far from a practical replacement for leading hardware.
